Errors (<number>):Could not allocate the following pins to any bank: - <number> pins at <voltage> mV" in the Early Power Estimator Intel® Stratix® 10

Due to a problem with the Early Power Estimator (EPE) Intel® Stratix® 10 version 19.4 and earlier, you may see this error even if the total number of used pins in the IO tab is within the maximum GPIOs.  

You can ignore the error and this problem won’t affect your power estimation result.

You can see the correct maximum GPIOs in the respective Intel® Stratix® 10 product family overview below.
